3 Claims.

This invention relates to improvements in tacking strips and a method of making such strips.

Heretofore great difiiculty has been experienced in securing tacking strips to metal plates, metal frames, etc., for example, it has been rather difficult to secure tacking strips tothe metal panels of automotive or other vehicles. To overcome such difliculty, it has been proposed to employ channeled panels adapted to retain the tacking strips in their channels, a construction which is expensive and not satisfactory. In addition, currently used tacking strips, generally made of fibre or wood, are rather stiff, cannot readily be bent, twisted or deformed, and do not give sufficient body for proper support of tacking nails.

It is the general object of the present invention to provide a new, simple and economic tacking strip which can readily and easily be secured to any metal support, is readily deformable and can be twisted or bent to any desired shape. Such general object of the invention is attained by the provision of a tacking strip made of metal screening, tightly wound to a roll of desired diameter and by rolling action shaped to the desired cross section.

A thus constructed metal screening tacking strip overcomes all disadvantages of currently used tacking strips, can be shaped to any desired cross section and bent to any form or shape without damage to the strip. The mesh of the metal screening used to make up the tacking strip and the number of supported layers of the screening in the strip determines its efiectiveness and can readily and easily be adapted to the desired purpose so as to permit of the use of any type of tacking nails for any particular job. Metal screening tacking strips can readily and easily be curved to any shape without increase in diameter by twisting and bending operations and can be welded or soldered to metal supports or attached thereto by means of screws if so desired.

With the above and incidental objects in View,

the invention consists in certain novel features of construction, the essential elements of which are set forth in the appended claims; and a preferred form of embodiment of the invention is hereinafter shown with reference to the drawing accompanying and forming a part of this specification.

In the drawing:

Fig. l is a perspective view of a metal screening tacking strip according to the invention.

Fig. 2 is a perspective View of a piece of wire screening or gauze partly wound up to indicate the making of the tacking strip.

Fig. 3 is a fragmentary plan view of a wire screening tacking strip welded to the curved edge 5 of a metal panel, the body of the tacking strip being twisted and curved so as tomake a perfect bend in the tacking strip without any deformation of the strip.

Fig. 4 is a perspective view, partly in cross section, of a channeled panel having a metal screening tacking strip according to the invention secured in a channel of the panel; and

Fig. 5 is a perspective View, partly in cross section, of a wire screening tacking strip shaped by rolling action to substantial semi-circular form with extended edge portions adapted to facilitate welding of the strip to a metal base.

Referring now more particularly to the drawing which illustrates a practical embodiment of the invention, I show a metal screening strip 2 made of metal screening 3 tightly wound up to an elongated strip. The mesh of the wire metal screening 3 is chosen in accordance with the tacking nails to be used for the particular purpose to afford proper frictional contact of the wire of the screening layers with the tacking nails. The wire screening wound to the strip 2 is secured to a support such as panel 4 by directly welding the strip to said panel (see Fig.

3) or the strip may be secured to a panel by means of bolt and nut attachments 5 (see Fig. 4)

Should it be desirable to countersink the tacking strip, the metal screening tacking strip 2 may be supported in the channel 6 of a panel I, in which case the strip may be forced into said channel to be held therein by frictional contact with the side walls of the channel or may be welded or secured to said panel in any other known manner.

The thus described metal screening tacking strip is slightly resilient and can readily be shaped to form any desired curvature by bending and twisting operations, the twisting eifecting a set of the strip to the desired curvature and controlling its cross section at the bent and twisted area.

Welding operations of a metal screening tacking strip to its support are materially simplified by shaping the round strip to a substantial halfcircular cross section (see Fig. 5) and bending the edges 8 of the half-circular strip 9 at right angles to the flat bottom ID of strip 9. This arrangement permits of the edges 8 being welded to a base without deforming the tacking portion 2. A tacking strip comprising a readily bendable body of a plurality of superposed layers of wire screening, said layers each having interengaged, yielding metal weft and warp strands adapted to clutchingly grip nails forced into said strip.

3. A tacking strip comprising a wire screening tightly Wound to a circular, elongated elastic body having a plurality of superposed layers of wire screening.
